Specification forming part of Letters Patent No. 44, [46, dalcdseptember6, 1864.

- To all whom it may concern.-

Be it knownthat I, THOMAS GRASON, of Manchester, in the county ofLancaster, in the Kingdom of Great Britain and Ireland, have inventedcertain Improvements in Boots, Shoes, and Other Coverings t'or'the Feet;and I do herebydeclare the following to be a full, clear, and exactdescription of the same, reference being had tothe accompanyingdrawings, and to the letters of reference marked thereoln p My inventionrelates to the novel method of securing outer sole and heel piecesto'the inner solesor upper-leather in boots, shoes, and'other coveringsfor the feet, whereby such sole and heel pieces can be detached or removed,when required, and fresh ones'attached atthe pleasure of thewearer, ad libitum.

The improvenientconsi'sts in the adaptation and meet T or V shapeddovetailed circular or other similar-termed ribs, elongated projectionsor runners, and corresponding grooves or channels, as a means ofconuect'ionbetween the upper part and the sole and heel of the boot.

In order to enable others skilled in the art to make my invention, Iwill now proceed to describe the manner of carrying the same intoetfeet.

On reference to the accompanying drawings, which form a part of thisspecification- Figure 1 represents the under side of a boot or shoehaving a dovetailed groove formed therein, and Fig. 2, is an inside viewof the outward sole detached, having ribs or projections'formed thereoncorresponding to the grooves or channels in Fig. 1. Figs, 3 and 4 arerespectively transverse sections of the upper and-under soles whenattached together, the upper plate in Fig. 3 having an open slot orgroove and that in Fig. 4 having dovetailed grooves or slots formed inthe solid metal. These grooves may either run transversely orlongitudinally on the sole of the boot. Fig.5 isapla-n view ot' theheel, showing the circular T or dovetailed grooves, having a number ofsliding pieces therein placed.

Fig. 6 is a side section of such groove and a sliding piece with acricketers spike thereto attached; Fig. 7, a section of the two plates,the bottom or sliding plate being provided with three descriptions ofprojections which may be worn in place of outer-soles. Fig. 8 is a viewof the upper plate, to which the heel or sole is attached, supplied witha projecting. bead or flange around its outer edge, forthe purpose ofshielding the sliding plate to which the heel or sole is'attacbed, alsogiving the appearance of one plate. Thisarrangement may' be reversed,it' desirable-that is to say, forming the flange on the under or slidingplate. Fig.

-9 is a side view of the heel, showing the method of fixing the bottomsole or heel by means of screws.

a a, Fig. 1,- is the inner welt or sole, and I the outer sole. shapedgrooves into which are keyed the corresponding ribsor projections, d,for the purpose of locking such soles together. When the outer sole andheel have been firmly forced up into their right position, aspring-latch, I, or other convenient fastener, is caused to retain themin such position until removed, at the wearers pleasure.

In Fig. 9, f is a metal plate secured in any conyenient manner to thewelt a. This metal plate f is the medium whereby the outer sole.

being accomplished by the screws g.

In Figs. Sand 6, h is the circular dovetailed groove, having slidingpieces i placed therein. These sliding pieces may be made to receive ascrew, k, having a spike, square or any other convenientform of head,ormay be made solid, of any materiahand to project below the groove,- asseen at m, or another modification of the same, as shown in Fig. 7,wherein screws are let through and countersunk into, the under slidingplate. 'lhese screws may have any desired form of head screwed ontothem, a, a and n being three descriptions of such projections, whichmaybe worn in place of outer soles.

Fig. 10 is another modification of my at tachable and detachable heel.

either by a screw going through it into the leather, or it may befastened by the plate a 0 is the dovetail or other I), is secured to thewelt, such means of fixture Fig. 11. is a back View, and Fig. 12 a sideview of the same.

being turned upward at right angles at the front, heaving two or morescrews securing it to the front of the heel.

The plates for the heels being made alike,

they may be changed from right to'left, or

- s lid invention, together with the method of c irrying the same intopractical efl'ect, I wish it to be distinctly understood that I do notconfine myself to the precise details, relative proportions, ordimensions hereinbeforc described, as it will be readily seen that thesame may be considerably varied without departing from the invention;but

What I claim as my invention, and desire to secure by Letters Patent,isp Securing sole and heel pieces to the soles and upper-leather ofboots and shoes and other coverings for the feet by the use ofdovetailed or T-shaped projections and grooves, substantially as and forthe purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

THOMAS- GRASON.
